this note describes how to set-up an SPI interface between the ASDP-2191 and an A/D converter (AD7476) in both hardware and software
This document provides technical guidance on establishing a Serial Peripheral Interface (SPI) connection between the Analog Devices ADSP-2191 digital signal processor and the AD7476 analog-to-digital converter. It details the hardware configuration, including pin connections and voltage level considerations for interfacing the two devices.
The guide also covers the software implementation required to control the SPI port on the ADSP-2191. It explains how to configure system registers, set interrupt priorities, and write assembly or C code to manage data transfers between the master DSP and the slave ADC.
The document describes how to set up an SPI interface between the ADSP-2191 and an A/D converter (AD7476) in both hardware and software.
The part operates from a single power supply up to 5.25V.
The output from the reference is a steady voltage (4.096V).
